Well, it's a matter of how you ask them, but anyway newcomers
are welcome here.

The simplest way is explicitly:

    z = (x[0]+y[0], x[1]+y[1])

There's not a really direct way to do it.  Tuples aren't vectors.

Python does support complex numbers if that's what you want:
   
   x = 1+2j   # Python uses "j" for sqrt(-1)
   y = 3+4j
   z = x + y
   print z
